“Relics” have been added for the Druid, Paladin, and Shaman classes to use in the ranged slot.

“Final Destination” Flight Paths—users can now select a flight path to automatically go to a destination that requires multiple flights.

Experience to Gold for L60 characters—users at L60 will now get gold compensation instead of experience.

A bunch of other stuff, including UI tweaks, class related changes, and raid changes.

The flight plan changes will definately make it easier to travel great distances, and the Level 60 changes give a little more motivation to get one’s characters up to the level maximum, particularly in preparation for the new level caps and content in the upcoming Burning Crusade expansion.
